Scope of the Manual

This Instruction Manual provides installation, startup

and maintenance procedures for the Type ACE95jr

tank blanketing valve. See Figure 1.

Product Description

The Type ACE95jr tank blanketing valve is an

extension of the Type ACE95 tank blanketing valve

and is intended to handle lesser ows on gas

blanketing systems. The valve prevents a stored

product from vaporizing into the atmosphere, reduces

product combustibility and prevents oxidation or

contamination of the product by reducing its exposure

to air. The Type ACE95jr maintains a slightly positive

pressure and thereby reduces the possibility of tank

wall collapse during pump out operations.

Type ACE95JR

Principle of Operation

The Type ACE95jr tank blanketing valve controls the

vapor space pressure over a stored liquid. When liquid is

pumped out of the tank or vapors in the tank condense,

the pressure in the tank decreases. Tank pressure is

sensed by the large actuator diaphragm. When tank

pressure is less than the valve set pressure, spring force

moves the actuator diaphragm downward.

When the actuator moves downward, it pushes open the

valve plug which allows ow in to the tank (See Figure 2).

When pressure in the tank increases above the setpoint,

the large actuator diaphragm is pushed upward, allowing

the valve plug to close.

The valve plug is balanced (inlet pressure equal upward

and downward force on these components); therefore,

the outlet (control) pressure of the unit is not affected by

uctuating inlet pressure.

Installation

WARNING

Personal injury, equipment damage or

leakage due to escaping accumulated

gas or bursting of pressure-containing

parts may result if this gas blanketing

system is over pressured or installed

where service conditions could exceed

the limits given in the Specications

section and on the appropriate

nameplate or where conditions exceed

any ratings of the adjacent piping or

piping connections.

To avoid such injury or damage, provide

pressure-relieving or pressure-limiting

devices (as required by Title 49, Part 192,

of the U.S. Code of Federal Regulations,

by the National Fuel Gas Code Title 54

of the National Fire Codes of the National

Fire Protection Agency or by other

applicable codes) to prevent service

conditions from exceeding those limits.

Additionally, physical damage to the

tank blanketing system could result in

personal injury and property damage due

to escaping accumulated gas. To avoid

such injury and damage, install the tank

blanketing valve in a safe location.

This Type ACE95jr tank blanketing valve was

assembled and preset to the customer specied

pressure and setpoint. The control pressure range of

the valve is stamped on the nameplate fastened to the

upper actuator case. The gas blanketing setpoint is the

only adjustable feature on this unit.

1. Get a qualied personnel when installing, operating,

and maintaining valves. Before installing, inspect

the valve and tubing for any shipment damage or

foreign material that may have collected. Make

certain the body interior is clean and the pipelines

are free of foreign material. Apply pipe compound

only to the male pipe threads with a screwed

body or use suitable line gaskets and good bolting

practices with a anged body.

2. Inspect the nameplate on the upper actuator

case. It displays the model number, serial number,

a blanketing gas supply pressure range, the

maximum inlet pressure, set pressure and CV

value. These must agree with the system that you

are blanketing. The serial number will be needed in

any communication with your local Sales Ofce.

3. Clean the gas blanketing supply lines of all dirt

and foreign material before connecting them to the

Type ACE95jr tank blanketing valve.

4. The valve must be mounted so the actuator case is

horizontal, as shown in Figure 3. The valve should

be mounted above the tank. Three connections are

required: a) blanketing gas supply to valve, b) valve

outlet to tank and c) sensing line to tank.

Type ACE95JR

Piping Considerations

Note

Piping lengths are best when they are

kept short with a minimum number of

elbows and ttings.

Inlet Piping

CAUTION

Undersized piping may inadequately

deliver blanketing gas at the

specied inlet pressure under full

ow conditions. This may result in

unacceptable performance under high

demand conditions.

The blanketing gas supply line should be equipped with

a Number 100 mesh strainer to remove dirt and pipe

scale. Inlet piping must be sized to adequately deliver

blanketing gas at the specied inlet pressure under full

ow conditions.

Outlet Piping

CAUTION

Unnecessarily long or restricted outlet

piping may result in poor setpoint control.

Valve outlet is piped into the tank vapor space. Outlet

piping must be full size and self-draining to the tank.

The valve should be situated above and as close as

possible to the tank vapor space for best performance.

Sensing Line

The sensing line should be 1/2 in. / 13 mm tubing or

pipe, must slope toward the tank and should not contain

low points (or traps) that could catch liquid. The sensing

line must enter the tank above the liquid level at a point

that senses the vapor space pressure and is free from

turbulence associated with tank nozzles or vents.

Note

Best control is obtained when both

connections to the tank are separate.

If the tank has only one available

nozzle, contact Emerson™. for alternate

methods of installation. A single array

manifold is available for such situations.

Gauges and Shuto Valves

Inlet gas shutoff valves are desirable for servicing.

If this Type ACE95jr tank blanketing valve was not

ordered with an inlet pressure gauge, it is advisable to

install a gauge between the inlet shutoff valve and the

blanketing valve.

Note

Safety considerations may dictate full

port shuto󰀨 valves between the tank and

blanketing valve and at the valve inlet.

Startup, Adjustment and Shutdown

Note

Tank vents and safety relief valves must

be in place and operating.

Startup

CAUTION

Always open the outlet valve before

the inlet valve. Operation in the reverse

order could result in inlet pressure being

applied to the actuator casing, potentially

damaging it.

1. Open shutoff valves between the blanketing valve

and the tank (both sensing and outlet). See Figure 3.

2. Slowly open the supply line shutoff valve (to the

blanketing valve) and leave it fully open.

3. Monitor the tank vapor space pressure.

Adjustment

The setpoint of this unit is factory set. Adjustments

should be made in small increments while the unit is

supplying gas to the tank. To change the setpoint:

1. Remove the actuator cap (key 1) from the top of

the spring case (key 7). See Figure 4.

2. Loosen the lock nut (key 3) and turn the adjusting

screw (key 2) clockwise to raise the setpoint.

(Turning the screw counter-clockwise lowers

the setpoint.)

3. Observe the effects of the change.

4. When the adjustment is complete, tighten the lock

nut (key 3) and replace the actuator cap (key 1).

Type ACE95JR

Shutdown

Installation arrangements vary, but in any installation

it is important to open and close valves slowly. When

shutting down the system, close the upstream supply

shutoff valve rst. Refer to Figure 3.

Maintenance

Valve parts are subject to normal wear and must

be inspected and replaced as necessary. The frequency

of inspection and replacement of parts depends on the

severity of service conditions and the requirements

of local, state and federal regulations. Due to the

care Emerson™ takes in meeting all manufacturing

requirements, use only replacement parts manufactured

or furnished by Emerson.

All O-rings, gaskets and seals should be lubricated with

a good grade of general purpose lubricant and installed

gently rather than forced into position. Approved

lubricant, sealants and adhesive are

as follows:

Lubricant: Dow Corning®111

Disassembly and Assembly

CAUTION

Before removing the valve from the line,

ensure that it is isolated from the gas

supply pressure and that all pressure

has been released from the valve. (The

drain on the inlet lter is convenient

to bleed o󰀨 gas.) All tank connections

must be closed or sealed in accordance

with your plant’s operating and safety

procedures. If installed, electrical

connections to the explosion proof

switch must be deactivated before

opening the enclosure or disconnecting

the wiring (in accordance with codes

and safety practices).

It is recommended that all seals and diaphragms be

replaced as a matter of good practice whenever a

valve is disassembled and re-assembled. Parts kits

are available through your local Sales Ofce.

Note

When ordering parts, have your model

number, serial number and control

pressure range. Valve information is on

the nameplate (attached to the upper

actuator case).

When performing disassembly or re-assembly

operations, refer to Figure 6 for key numbers (unless

otherwise directed).
